LOOM TEMPLE Filed Oct. 10, 1928 Jhveniar Wad M Patented Mar. 31, 1931 UNITED STATES PATENT OFFICE JONAS NORTHROP, OF HOPEDALE, MASSACHUSETTS, ASSIGNOR. TO STANDARD LOOMS, INC., OF MILFORD, MASSACHUSETTS, A CORPORATION OF SOUTH CAROLINA LOOM TEMPLE Application filed October 10, 1928. Serial No. 311,523.

The present invention relates to loom temples. v

The object of the present invention is to reorganize and improve loom temples, and particularly thread severing devices therefor, with a view to simplicity and economy in manufacture and reliability in operation.

To this end, the present invention consists of the loom temple hereinafter described and particularly defined in the claims.

In the accompanying drawings illustrating what is now considered the preferred form of invention, Fig. 1 is a rear elevation of so much of a temple as is necessary to an understanding of the invention; Fig. 2 is a section on line 2-2 of Fig. 4; Fig. 3 is a sectional view similar to Fig. 2, showing the thread severing device in closed position; Fig. 4 is a section on line 44 of Fig. 2; and Fig. 5 is a section on line 55 of Fig. 2.

The illustrated embodiment of the invention comprises a temple frame or shell consisting of a pod 6 and cap 8, a heel 10, and slide bar 12. The toothed rolls 14 are journaled in the pod on shafts 15. The cap is enlarged at its outer end, as indicated at 16, and the pod and cap are secured together by a bolt 18. The cap has a recess to accommodate the thread severing device which is 1 indicated generally at 22. A plate 24 is secured to the outer end of the cap by the bolt 26 and has a plurality of vertical openings or slits 28 opposite the thread severing device 22. Through these slits extend the separate '5 blades 30 of the thread severing device. The

plate 24. bears at the top and along its sides and bottom against the cap and pod. That part of the pod below the recess 20 is of reduced thickness to afford a recess 32 between the pod and the plate 24 in order to accommodate the blades 30 when the thread severing device is in closed position, as shown in Fig. 3.

Referring specifically to the thread severing device, it is a casting of the general form shown in Fig. 2, being pivoted on a bolt 34 threaded into the cap. An elongated portion 36 of the thread severing device extends forwardly and then downwardly to form the hunter 38 which is adapted to be engaged by the lay 40. The weight ofthe elongated portion 36 and the hunter 38 places thecenter of gravity of the thread severing device considerably forward of the pivot, in order that the device will be normally maintained by gravity in open position with the blades raised, as shown in Fig. 2. The blades 30 are of sharpened steel, each having a forward end portion 31 which is cast in the body of the thread severing device, thus accurately positioning them to assure their proper register with the slits 28 at all times. As shown in Figs. 1 and 5, the blades extend loosely through the slits 28, that is to say, they pass freely through the slits and have no engagement with the plate 24. The blades, therefore, constitute a thread breaker as distinguished from a thread cutter, in which the thread is severed by a scissors action. The

two outer blades act when the hunter 38 is engaged by the lay, to engage the thread and draw it through their corresponding slits. This action places a' tension, on the thread which is broken by the engagement of the middle blade therewith. The blades are shown as being three in number, although more blades may be employed if desired. Be cause of the free passage of the blades 30 through the slits 28, the thread severing device readily returns to its open position under the influence of gravity when the lay is retracted.

.As shown in Fig. 2, the plate 24 does not completely enclose the pod at the bottom but leaves an open space 40 through which pieces of lint may drop, thus preventing clogging or sticking of the blades in operation.

In order to prevent striking of the blades against the pod as the thread severing device closes, a guard plate 42 is riveted to the hunter 38 and is arranged to engage the heel 10, thereby preventing overthrow of the thread severing device, which might result in injury to the blades as by burring or bending them.

It will be seen that the thread severing device of the present invention, operating as it does only under the influence of gravity, avoids the necessity for springs or other mechanical expedients to restore the parts to open position after a severing operation. The number of parts required, and consequently the cost of manufacture are greatly reduced. Moreover, the invention possesses the advantage that in operation, there is no danger of broken springs, which might require replacement from time to time. In addition, the free movement of the blades as sures certain return to open position, without possibility of sticking under any circumstances.

Having thus described the invention, what is claimed is 1. A loom temple having, in combination, a cap, a heel, a thread severing device provided with a plurality of blades and pivoted on the cap, a hunter on the thread severing device, the thread severing device being adapted to be normally maintained in open position by gravity, a plate mounted on the cap and having openings through which the blades extend, and a guard attached to the hunter and adapted to engage with the heel to prevent overthrow and striking of the blades on the cap.

2. A loom temple having, in combination, a cap, a heel, a thread severing device provided with a plurality of severing blades pivoted on the cap, a bunter on the thread severing device, the thread severing device being adapted to be normally maintained in open position by gravity, the cap having a plurality of openings into which the blades extend, and guarding means connected with the bunter of the severingdevice adapted to engage a stationary part of the cap to prevent overthrow of the blades on the cap.

In testimony whereof, I have signed my name to this specification.

JONAS NORTHROP.
